I'm looking to doing some hiking in Japan this fall. Not being quite as in shape as I'd like, I've dropped the idea of bringing film and I'm looking to update my digital camera. Right now all I have is the GF1 and 20mm lens. I'm planning on picking up the 9-18 (lighter and takes filters over the 7-14) and the 40-150. The latter seems sharper than the 45-200 near the extreme end of the zoom when stopped down and it's lighter. I'm not sure I'll need anything in between.
I'm curious what your thoughts are on the camera. If I keep the GF1, I'll probably have to buy another 2 or 3 batteries and I realize they aren't used in any of the newer camera. Do you think it's worth upgrading to a EP-3 or EPL-2/3? Having IBIS with the lenses would be welcome I think. I'm not if I expect much of a difference in image quality between the two.
Any thoughts, or considerations to photographing when climbing mountains?
I'm still debating on a tripod. I have a GT1550T with BH-30. Seems light now, but I wonder how it feel once I'm carrying it for a couple days. Anything else you'd recommend, or should I go without it?
